VENTILATED REFLECTOR.

Specification of Letters Patent.

vPatented Nov. 14, 1911.

Application led .Tune 17, 191.1. .Sera1 No. 633,790.

of New York, have invented certain .new Vand useful :[rriprovementsl in Ventilated Reflectors'; and I do hereby declare the following to be a full.` clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specilica'tion.

The present invention has reference, generally, to improvementsl in reflectors; and

' the invention relates, more particularly to a novel construction of ventilated reiiectorbody.

The present invention has for its principal object to provide a simple and eiiicient construction of reflector-body adapted to eliminate the descent of heat waves generated with the light rays of illuminating units used with said refiector, by interrupting and deecting the downwardly descending heat waves and absorbing the same in a cooling circulation of cool air interposed beneath said illuminating units and the locus of illumination. v

Other objects of the present invention, not

at this time more particularly enumerated, will be clearly understood from the following detailed description of the 'present invention.

With the'various objects of this invention in view the same consists, primarily, in the novel' ventilated reflector body hereinafter set forth; and, furthermore, this invention consists in the novel arrangements and combinations of the various devices and their parts, as well as in the details of the construction thereof, all of which will be hereinafter more fully described-in the following specification, and'then finally embodied in the clauses of thef'claim which arel appended to and'whichform aness'entialpart` of this specification.

The invention is clearly illustrated inthe accompanying drawings, 'in which AFigure 1 is a longitudinal vertical section of the novel construction of vventilated re-v ector bod made according to and embodying the principles of the present invention;

Fig. 2 is a detail horizontal section of the same taken on line 2-2 in said Fig. 1, looking in an upward direction; and Fig. 3 is a transverse cross section of the same taken on line 3 3 in said Fig. 1 looking in the direction of the arrow m. l

Similar characters of reference are em ployed in all of the hereinabove described views to indicate corresponding parts.

Referring now to the said drawings, the reference-character 1 indicates the complete reector madel according to and embodying the principles of the present invention, the same comprising a dome 2 from which depends a reflector shell 3 terminating at its lower portion in a downwardly depending surrounding a ron 4. Said reflector-shell 3 .is preferably formed to provide angularly cured and disposed hanger members 6, by

means of which said reflector may be suspended. The reference-character 7 indicates ahorizontally extending partition member lsupported within the interior of said dome 2. Secured to said partition-member 7 are a series of lamp sockets 8 from which depend downwardly, beneath said partition member and within said reflector-shell, a series of illuminating units 9. While the 'illuminating units shown in the drawings areof the electric incandescent type, it will be understood that any desirable kind of illuminating unit or units maybe used with thev novel reflector body, the illuminating `medium being electricity, gas, loil, or any Said partition.

other generating means. member 7 is provided with a plurality of suitably disposed holes or openings 10 providing 'communicating air passages between the interior 11 of said reflector shell 3 and vthe space or chamber 12 above said partition-member 7 within said dome .2. The upper or top wall of said dome 2 is also provided with a suitable number of conveniently disposed escape-holes or openings 13 through which the heated air may escape from they space or chamber l2 in the upper portion of said dome 2. The side walls of said dome 2 are also provided with a pluinterior 11 of said reflector-shell with the apron 4 of said reflector-shell 3,the

same being adapted to support a glass partition member or screen 16. ISaid partition or screen 16 being constructed slightly shorter than the length of said reflectorshell, so as to provide air-passages or open spaces 17 at each end thereof. 'Ihe locksc'rews 18 arranged operatively in the wall of said apron 4 are adapted to lsupport said partition member or screen in its raised or normal transversely extending position.

l The said apron 4 is provided with an out-A wardly extending bead 19 adapted to provide a guide-way .20 in which is slidably supported a frame-member 21 adapted to support a glass partition-member or screen 22, which registers below said partitionmember or screen junction therewith an intervening' air-space or chamber 23. One end of said apron 4 .is provided with an opening admitting said partition member or screen 22 to its guideway 20, the outer end of said frame-memb er 21 being provided With a handlep'ortion 24 for -slidably moving said partition member or screen 22, when it is so desired. Secured to the outer side of the Wall of the apron 4, at one end Iof said reflectorshell 3is distributer box or tube 25 providing an air chamber 26. Said .distributerA I '.box or tube 25 is provided throughout its I ber 23.

Ivening air length on one side with a series of nozzle 0r tubular extensions 27 which penetrate the wall of said apron 4 so as to afford communicating air passages between said air chamber `26 and said` intervening air-space or chamber 23. Said distributer box or tube 24 is provided with a tubular hose connectionl 28, whereby an air feed hose may be attached to said distributer box or tube 25 for thepurpose of supplying a cooling current of air to be passed through said interspace or chamber 23, or a suction hose may be attached for sucking'the air through said intervening air space or cham- 'Ihe opposite Wallof'said apron 4 is provided with `a series of ysuitably ditsposed holes or openings 29, providing air .escape passages through which the'air may pass either out ofor into the said inter- Y vening air space or chamber 23, according to whether forced draft or suction is applied through said air distributing, box or tube 25.

The ventilation of the novel reflector 'con-A structed as above described is accomplished as follows z-Air is supplied from any convenient source to said chamber 26 provided 16'and provides .in con# present invention,

by said distributer box ortube 25 and is thence distributed through said nozzles or tubular extensions 27 throughout the interior of said intervening air space 23, whence it escapes through said air passages 29, thus providing an intervening area of cool air interposed between said illuminatingy units and the locus to be illuminated, thereby preventing the descent of heat waves from within the reflector body. 'A portion of the `air introduced into said intervening air space 23 from said distributer box or tube 25 nds its way through the passages 17 lupwardly into the interior 11 of said reflector shell causing a circulation of cool air therein which carries off the heated air -through the respective openings or passages 14,10 and 13, which arelocated in the upper portions of said reflector body. Of course it will also be apparent that the process of ventilation may be'reversed that is the air may be suckedthrough the intervening air space 23, and the interior of said reflector shell, by lexhausting the air from said distributing box or tube 25, if such a manner of ventilation is found desirable.

rI`he construction of ventilated reflector 'above described is peculiarly adapted for use in the operating rooms of hospitals for illuminating the operating tables, and at the same time preventing the concentration of the heat generated by the illuminating units upon the patient and surgeons and attendf ants during operations. This construction is also adapted`^to be used (in operating rooms in which either increased air pressure is created, or a reverse condition such as the formation .of a vacuum, aswill be clearly evident. f

I am aware that changes may be made in the general arrangements and combinations of the devices and parts, as well as in the details of the construction of the same, Without departing from the scope of the as set forth in the foregoing specication, and as defined in the claims appended thereto. Hence, I do not limit my invention to the exact arrangements and combinations of the devices and ,parts described in said specification, nor do I confine myself to the exact detailsof the construction of the said parts as illustrated in the accompanying ,drawings I claim 1.
